The explanatory diagram of the experimental result of field trash intrusion in making.As shown in fig. 7, in experimental example 1~2, although for preventing ozzle
Slag attachment when being inserted into melt has effect, but in casting, has imported the field trash floated from below, moulding
In be mixed into field trash.Fig. 8 is the electron micrograph for having invaded the moulding of field trash, in Fig. 8, (A) be mixed into it is aerobic
Change the moulding of aluminium, (B) is the moulding for being mixed into carbon.In experimental example 1,2, due to being mixed into for field trash, moulding occurs
Cracking etc..On the other hand, in experimental example 3~5, it is known that further suppress the field trash intrusion in casting, closed
Suitable moulding.In particular, know if using experimental example 5 ozzle, be more highly preferred to.In addition, for Cu-Zr alloy,
It in order to form the nano lamellar tissue of high-intensitive and high conductivity, is highly desirable to prevent the intrusion of field trash, thus it is speculated that application is real
The meaning for testing the ozzle of example 3~5 is high.
[experimental example 6,7]
Next, being studied for the effect of the bubbling in field trash removal step.It handles and evaluates in above-mentioned casting
In test, it will be bubbled using Ar gas before carrying out vertical Continuous Up casting processing using the ozzle of experimental example 5
The manufacturing method of moulding be set as experimental example 6.In addition, in above-mentioned casting processing evaluation test experimental example 5 will be being used
Before ozzle carries out vertical Continuous Up casting processing, roused from drilling pipe (lance pipe) (Porous carbon) supply Ar gas
The manufacturing method (referring to Fig. 5) of the moulding of bubble is set as experimental example 7.So that side of the moulding as 80 μm of diameter of Cu-Zr silk
Formula has carried out rolling and mold wire drawing.Manufacture evaluation result is summarized in table 1.As shown in table 1, before casting process
In the experimental example 6 not being bubbled, break number up to 40, and average length is 2.1 ten thousand m.In contrast, it is carried out before casting is handled
In the experimental example 7 being bubbled, broken string number is 9, and average length is 9.5 ten thousand m, confirms its huge effect in the combination with ozzle
Fruit.
